Hi,

I printed it off from the Internet but unfortunately it doesn't have the website on it so I can't refer you on(nor acknowledge the source).

I'll type it here for you.

Black Walnut Hull Tincture

This new recipe is four times as strong as the previous one, so it is called Black Walnu Hull Tincture Extra Strength:
-Your largest enamel or ceramic (not stainless steel, not aluminium) cooking pot, preferably at least 10 quarts
-black walnuts in the hull, each one still at least 50% green, enough to fill the pot to the top;
-grain alcohol, about 50% strength, enough to cover the walnuts'
- 1/2 teaspoon Vit C;
-plastic wrap or cellophane
-glass jars or bottles

The Black-Walnut tree produces large green balls in fall. The walnut is inside, but we will use the whole ball, uncracked, since the active ingredient is in the green outer hull. Rinse the walnuts carefully, put them in the pot and cover with the alcohol. Sprinkle on half the vitamin C. Seal with platic wrap and cover. Let sit for three days. Pour into glass jars or bottles, discarding walnuts, and divide the remaining vitamin C amongst the jars.
If the glass jar has a metal lid, first put plastic wrap over the top before screwing on the lid. Potency is strong for several years if unopend, even if it darkens.

When preparing the walnuts, rinse only with cold tap water. You may need to use a brush on areas with dirt. If you are not going to use all of them in this batch, you may freeze them in a resealable plastic bag. Simply refrigerating them does not keep them from turning black and useless. The pot of soaking walnuts should not be refrigerated. Nor does the final tincture need any refrigeration.
Exposure to air does cause the tincture to darken and lose potency. To reduce air exposure, fill the pot as much as possible, without touching the plastic wrap. while still keeping a snug fitting lid. Even more importantly, the glass jars or bottles you use to store your tincture should has as little air space as possible without touching the plastic wrap on top. A large jar should be divided into smaller ones when you are ready to use it.
The idea is not to have partial jars, with a lot of air space, sitting for langer than a month or so.
There are several ways to make 50% graain alcohol solution. Some states have Everclean(TM)95% alcohol. Mix this half and half with water. Other states have Everclear that is 76.5% alcohol. Mix this 3 parts Everclear to one part water. Yet another method is to buy vodka that is 100 proof. This is already 50% alcohol.
Remember, never use any kind of purchased water to make tincture.

Black Walnut Hull Tincture (Regular Strength)
This is the potency I used originally. It is included here in case you prefer it or wish to treat a pet. The Extra Strength recipe is four times as potens as the original recipe, so it must be diluted in quarters.
Similarly, if you have a lot of the Regular Strength left and want to use it in place of Extra Strength, simply take 4 x as much.

-Grain alcohol about 10%
Mix one part extra strength tincture with three parts of the 10% alcohol. Store in glass containers same as described above.
There are several ways to make a 10% grain alcohol solution. Some states have Evercler(TM)95% alcohol. Mix this one part Everclear to 9 parts of water. Other states have Everclear that is 76.5% alcohol. Mix this one part Everclear to seven parts water. With Vodka that is 100 proff(50% alcohol) mix one part vodka with four parts water.



Hope this is helpful.
